iMPLEMENT FOR SECURING BUTTONS TO FABRICS.

SPECIFICATION forming part of Letters Patent No. 321,411, dated June 30,1885. Application filed January 27, 1885. (No model.)

To all whom it may concern.-

Be it known that we, ALEXANDER G. \VIL- KINS, of Meadville, in thecounty of Crawford and State of Pennsylvania, and J AMES B.

MILLER, of Kent, Portage county, and State of Ohio, have invented a newand Improved Implement or Machine for Securing Buttons to Fabrics; andwe hereby declare the following to be a full. clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making part of this specification, in which Figure l is a sideelevation showing abenchmachine embodying our improvements, the workingparts being in section. Fig. 2- is a detail of the removable adjustableclinchingdie.

In the class of buttonfastening machines to which our invention relatesit is highly desira- 2o ble that the clinching-die may be easilyreplaced when worn or broken, and it is also desirable to set themachine so as to make high or low loops, as the user may desire orrequire.

To this end our invention consists in a pc- 2 5 culiarly-constructedremovable clinching-die and an adjustable stop so arranged as to preventthe jaws of the machine from approaching each other beyond apredetermined point, all of which will be hereinafter fully described,

and specifically pointed out in the claim.

In order that those skilled in the art may make and use our inventi0n,wewill proceed to describe the manner in which we have carried it out.

5 5 For purposes of illustration we have shown our invention as appliedto a bench-machine having one jaw fixed and the other jaw adapted to beattached to a treadle by means of a connecting-rod, and havingaretractingspring to hold the jaws normally open, as is usually appliedto such bench-machines.

Ordinary mechanical appliances well known in the art and ordinarymechanical skill can convert the machine illustrated into a hand- 5machine without departing from the spirit of our invention.

In the said drawings, A A are the jaws,pro vided with barrels B E,caston their ends, the barrel B containing the springbolt O, provided on itslower end with a spring button holding latch, D, and the barrel Bcontaining the telescopic spring fastener-holding device E, the detailsof which it is not necessary in this patent to describe.

Immediately behind barrel B the jaw is bored at a, and length wise themachine, through the hole so bored, is out a slot, 1), the slot 12 andthe lower portion of hole a being ina lump or projection, F, castintegral with the head. The slot Z) is in line with and behind a slot,(1, out in the sliding bolt 0 to receive the upsetting-die.

The upsetting-die consists of a shank, 6, having its upper end threadedatf, and carrying in its lower end a thin metallic piece or 6 blade, H,one edge of which rests within slot d in barrel B and bolt 0 when theshank e is inserted into hole a, and secured by not a. The lower cornerof the edge of blade or piece H, which projects into slot (1, is cutaway in a 0 curved line, as seen at i, and the face of this curved edgeacts on the point of the fastenerpin and coils it around the button-eye.The construction of the bearingsurfaces of this upsetting-die and thesocket to receive it make it exceedingly easy to manufacture, strong andsteady in operation, and easily removable and interchangeable. Moreover,it can be easily and quickly ad j usted with the other working parts ofthe machine.

In order that the loops of the fastening-pins may be left ofapredetermined length when finished, I provide between the projectionsof the jaws, behind the pivot y, an adjustable stop, I, which in thepresent instance is shown as resting in a bracket or lump, K, cast onthe stationary jaw-piece of the machine. The adj ustable. stop I is abolt having a screwthread, k, on its lower end, which the bracket K istapped to receive. The upper end of the 0 stop I being in the line oftravel of the approaching jaw extensions or arms, one jawarln brings upagainst it upper end, and furupsetting-die provided with shank e, andther approach of the jaws is stopped and any curved corner 1', allconstructed substantially further crushing down of the loop prevented.as set forth.

By screwing stop I into the bracket and 7' T 5 withdrawing it, theposition of its upper end i F is changed so as to stop the approach ofthe 1 jaws at any desired point. Vitnesses to \Vilkins signature:

Having thus described my invention, what 0. M. BOUSH, I claim as new,and desire to secure by Letters OTTO A. SToLZ.
